Diplomatic Doubletalk

October 18, 1985

MANILA, PHILIPPINES — ''Cordially and mutually beneficial,'' a U.S. Embassy press release said. ''A frank exchange of views'' was the statement from the presidential palace. It showed that President Ferdinand Marcos was irritated at U.S. criticism of his government. Marcos met twice with Sen. Paul Laxalt on Wednesday and Thursday, and the Nevada Republican delivered a message from President Reagan. Sources said Reagan is particularly concerned about a growing communist insurgency, fed by the deepening economic problems and corruption under the Marcos government. The United States has been pressuring Marcos to hold ''credible'' elections, to make changes in the military and has indicated displeasure with conduct of the trial of 26 men accused in the killing of opposition leader Benigno S. Aquino Jr. in 1983.
